Spin-flip Raman laser at wavelengths up to 16.8 μm

Abstract
An InSb spin‐flip Raman (SFR) laser is pumped with an optically pumped NH3 laser line at 780.515 cm−1 to obtain tunable first Stokes laser radiation at wavelengths up to 16.8 μm. We report results on the power output, tunability, and preliminary spectroscopy of UF6. Scaling of the primary CO2 pump laser as well as the NH3 laser together with the SFR laser appears possible for potential application of this system to uranium isotope separation.
